10(x−2)+15=8x+7

 Simplify

10(x−2)+15=8x+7

(10)(x)+(10)(−2)+15=8x+7(Distribute)

10x+−20+15=8x+7

(10x)+(−20+15)=8x+7(Combine Like Terms)

10x+−5=8x+7

10x−5=8x+7

Subtract 8x from both sides.

10x−5−8x=8x+7−8x

2x−5=7

Add 5 to both sides.

2x−5+5=7+5

2x=12

Divide both sides by 2.

2x/2 = 12/2

x=6
